Pigmentary glaucoma, left eye, moderate stage

This code signifies a specific type of secondary open-angle glaucoma affecting the left eye, characterized by pigment dispersion that obstructs the trabecular meshwork. The condition has progressed to a moderate stage, indicating a measurable degree of optic nerve damage and visual field loss.

Apply this code when documentation confirms a diagnosis of pigmentary glaucoma in the patient's left eye, and the ophthalmologist has staged the condition as moderate. Supporting documentation should include visual field test results, optic nerve head evaluation (e.g., OCT, fundus photography), and intraocular pressure readings.

• Ensure laterality is accurately documented; do not use for bilateral or right eye involvement.
• Verify the stage of glaucoma (mild, moderate, severe, indeterminate) is explicitly stated by the physician.
• Always code the underlying cause of the glaucoma (e.g., pigment dispersion syndrome) if separately documented and clinically relevant.
